A Pressure Load represents single component pressure acting on a surface of a nodal flexible body. A Patchset must be specified to create the pressure. A Pressure Load calculates its pressure based on user-specified Function Expression or User Subroutine. A force generated from the pressure is applied on all nodes belonging to the Patchset. The reaction force is zero. The direction of the force can be determined from the normal direction to the surface. This force is available for shell and solid elements.
